Product Overview

Air Operated Pinch Valves

See how the AKO Air Operated Pinch Valves work:

Characteristics of Free Flow Air Operated Pinch Valves:

Air operated pinch valves are operated by supplying compressed air or fluid into the housing, which compresses the rubber sleeve/liner. The special manufacturing process of the sleeves ensures high rebound elasticity. The rubber sleeve closes in the same way every time due to the elliptical design of the body, forming a lip shape to ensure a completely tight shutoff of the product flowing through (even with large solids). This guarantees the longest service life of the rubber sleeve/liner, and results in energy savings.

The maximum operating pressure for all AKO air operated pinch valves is dependent on the nominal diameter and is around 2-6 bar. As soon as the supply of compressed air or fluid is interrupted and the valve casing is vented or drained, the durable rubber sleeve is opened by its rebound elasticity/resilience, enabling the pressure in the medium to flow through the full passage of the air operated Pinch Valves.
